[Frame text not behaving correctly]

Thanks for your help.

When I select the text frame, there is not a check mark in the box for the"No Break" option in the Character pallet. Also the value in the leading override box is set to zero. I just opened up a new document and used the text frame tool and had the same result, with No Break and leading override set to zero. 

[Frame text not behaving correctly]

I am new to Affinity Designer and Publisher so I may have something setup wrong. When using the frame text tool in Designer, I am unable to get the text to automatically flow to the next line when it reaches the end of the frame. Also, when I try to utilize a soft return (option+shift+return) to force the the text to the next line, the text starts again on the same lime. Attached are screen shots, the 1st showing the text not dropping to the next line in the frame, and the 2nd showing the text starting again on the same line when using a soft return.

What am I missing or doing wrong? Thanks or your help.
